摘　　要：针对山东某含碲含碳难处理金矿进行了选矿试验研究,结果表明:采用原矿全泥氰化、浮选、浮选-氰化联合流程,金回收率均不理想;采用原矿焙烧-焙砂氰化浸出工艺,可获得金回收率90.82%的指标,实现了金的高效回收。An experimental research was carried out on a refractory gold ore containing Tellurium and Carbon in Shandong Province.The results show that the gold recovery index is not ideal by using processes such as cyanide leaching,flotation and flotation-cyanide leaching combined process.The gold recovery rate of 90.82% can be obtained by using raw ore roasting-cyanide leaching process,and the high-efficiency recovery of gold can be realized.
